After a 6 month hiatus, I am back on Adderall. It's been about a week since I started taking it and I am prescribed the orange generic version 20 mg , 2 times a day . In the past, my side effects have always been mild. Today I noticed that there are two lumps underneath my right armpit. One medium sized, the other fairly small. There is also some light sore pain in a small section of my neck ( in between the top of my jawbone and right ear lobe ) Both the armpit and neck pain is on the right side of my body. My knuckles/ fingers are also certainly a little bit more red then usual. I will see a dr. soon but would like to know if any of you think this is related or if anyone has had any similar problems? I have a pretty serious case of add and Adderall has certainly helped me in the past. I will be prepared to stop if this is really harming me but hope it's not the case. Anyway, any information you could give me would really be appreciated .
